Symplectic Perturbation Theory in Massive Ambitwistor Space: A Zig-Zag Theory of Massive Spinning Particles
Joon-Hwi Kim, Sangmin Lee
We develop a theory of massive spinning particles interacting with background fields in four spacetime dimensions in which holomorphy and chirality play a central role. Applying a…
Pattern recognition with a magnon-scattering reservoir
Lukas Körber, Christopher Heins, Tobias Hula +4
Magnons are elementary excitations in magnetic materials and undergo nonlinear multimode scattering processes at large input powers. In experiments and simulations, we show that th…
Resonant dynamics of skyrmion lattices in thin film multilayers: Localised modes and spin wave emission
Titiksha Srivastava, Yanis Sassi, Fernando Ajejas +9
The spectral signatures of magnetic skyrmions under microwave field excitation are of fundamental interest and can be an asset for high frequency applications. These topological so…
Synchronization of chiral vortex nano-oscillators
Zhiyang Zeng, Zhaochu Luo, Laura J. Heyderman +2
The development of spintronic oscillators is driven by their potential applications in radio frequency telecommunication and neuromorphic computing. In this work, we propose a spin…
Effects of delayed feedback on the power spectrum of spin-torque nano-oscillators
Jérôme Williame, Joo-Von Kim
A theoretical study of delayed feedback in a spin-torque nano-oscillator model is presented. The feedback acts as a modulation of the supercriticality, which results in changes in…
Spin-torque induced wall motion in perpendicularly magnetized discs: ballistic versus oscillatory behavior
Paul Bouquin, Joo-Von Kim, Olivier Bultynck +4
We use time-resolved measurement and modeling to study the spin-torque induced motion of a domain wall in perpendicular anisotropy magnets. In disc of diameters between 70 and 100…
